SPECIFICATION forming part of Letters Patent No. 786,205, dated March28, 1905. Appli i n fi September 1, 1904. Serial No. 223,009-

To all whom it may concern;

Be it known that I, AUGUST GERrI-I, a citizen of the United States,residing at Estelline, in the county of Hamlin and State of South 5Dakota, have invented new and useful Improvements in Fanning-Wills, ofwhich the following is a specification.

My invention relates to improvements in fanning-mills.

Said invention has for its object to provide for the cleaning of grainin an expeditious and effective manner and to simplify the constructionof parts and to cheapen the manufacture of the same; and to these endssaid invention I consists of certain structural features, substantiallyas hereinafter more fully disclosed, and particularly pointed out by theclaims.

In the accompanying drawings, illustrating the preferred embodiment ofmy invention,

Figure l is a side view thereof. Fig. 2 is a vertical sectionalelevation produced longitudinally of the machine. Fig. 3 is a plan viewthereof. Fig. 4 is what may be called a rear end elevation of the same,and Fig. 5 is a ver- 5 tical transverse section in part of the machineproduced through the rotary sieve or screen. Fig. 6 is an enlargedbroken perspective view showing more fully the idler pulleys forchanging the direction of the sieve or screen 3 actuating belt.

In the carrying out of my invention I provide a suitably-constructedupright frame 1, within which is arranged the operative parts thereof,said frame also having secured thereon a feeding-hopper 2.

A cylindric sieve or screen 3, arranged just below the hopper 2, isrotatably mounted in position by means of, and has passinglongitudinally therethrough, a journal or shaft 4,

4 said shaft bearing in and passing through cross-pieces 5 5,respectively, one being fixed between parallel lateral bars 5", securedto the uprights of the frame 1. The other crosspiece, 5, is adjustablesubstantially vertically, as and for the purpose presently described.Said sieve or screen 3 has the head 3 thereof at its receiving endproduced with a feed-opening 3, into which extends the lower end of aspout or chute 2, secured centrally to the bottom of the hopper 2 todeliver the 5 contents of the last noted into said sieve or screen fortreatment, as later disclosed. I Vithin said sieve or screen andsuitably secured thereto a short distance inward from and opposite tosaid feed-opening is a disk or bracket 3, through which passes, andprimarily serv-- ing as a support for, the shaft or journal A at thatend of said sieve. The opposite end of said sieve has suitably heldthereto a pulley 6, loosely through which passes the shaft or journal4;, and which pulley is engaged or driven for rotating said sieve by anendless belt 7, whose upper and lower portions engage rolls or idlers 8,arranged upon a common journal or shaft 8, suitably secured upon 5 thecross-piece 5, said belt also engaging and being driven by a pulley 9,secured upon a handled shaft 10, suitably journaled upon the lateralbars 5". Upon the shaft 10 is also secured a large wheel or pulley 11,the purpose 7 of which will appear later. The adjustability of thecross-piece 5 is provided for by the disposing of its end portionswithin vertical slots 5 more or less curved for obvious reasons,produced in upstanding arms or bars 5, secured to the lateral bars 5'and by adjustingpins 5 inserted through holes or perforations 5?,provided in said arms, and perforations 5 in said cross-piece 5, as willbe readily appreciated. This arrangement provides for the 30 consequentadjustment of the rotary sieve according to the declination it may berequired to give the same, as in treating or cleaning small or largegrain the smaller the grain the greater the declination; consequentlythe 5 larger the grainthe less the inclination.

A rotary fan 12, whose casing or housing is suitably secured in positionand having a chute or tapered extension, is driven by an endless belt13, engaging a pulley 12 on the 9 fan-shaft and the pulley or wheel 11on the handled shaft 10, from which it will be noted that a blast may begenerated simultaneously with the actuation or rotation of the sieve 3and said blast be delivered upon, and thus dispose of the chaff fallingfrom, said sieve as the grain is being treated within the last noted.

Suitably suspended, so as to be vibrated, below the rotary sieve orscreen 3 is a forwardly-inclined rectangular screen or sieve 14,receiving whatever of the grain treated Within said rotary sieve fallingtherethrough and suitably delivering the same as may be required, thebody or bulk of the grain after treatment by the rotary sieve beingdischarged therefrom out through its rear end, as will be seen.

Latitude is allowed as to details herein, as they may be changed ascircumstances suggest without departing from the spirit of my invention.

I claim- 1. A device of the character described, employing a sieve orscreen rotatably mounted in position, a shaft for said sieve or screen,upstanding arms suitably secured in position, and bearings for saidshaft or journal, one being a cross-piece received in vertical slots ofsaid upstanding arms, said arms and said shaft-bearing having adjustingperforations, and adjusting-pins adapted to engage said perforations,said cross-piece bearing a shaft equipped with pulleys, a handle-shaftcarrying a pulley, and an endless belt engaging said pulleys.

2. A device of the character described, employing a sieve mounted inposition, a shaft for said sieve or screen, and bearings for thesieve-shaft suitably supported in position, one being adjustable, saidrotary sieve or screen having fixed to its shaft a pulley and saidadjustable bearing carrying a vertical shaft equipped with pulleys, ahandled shaft carrying a pulley, and an endless belt engaging porting anadditional shaft equipped with pulleys, a handled shaft carrying apulley,

and an endless belt engaging said pulleys.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

AUGUST GERTH. Witnesses:
